Low-Altitude Passive Integrated Sensors (LAPIS)

Low-Altitude Passive Integrated Sensors (LAPIS) is sponsored by Department of the Army. Develops a passive integrated sensor system for low-altitude UAS detection and tracking.

This topic seeks to develop a solution that passively detects and identifies small unmanned aerial systems (sUAS) at low altitudes and various velocities. The objective of this effort is to increase the advance warning time of small incoming threats for ground-based units. </p> <p>This topic is accepting Direct to Phase II proposals for a cost up to $2,000,000 for a 24-month period of performance.

</p> <p>Proposers interested in submitting a DP2 proposal must provide documentation to substantiate that the scientific and technical merit and feasibility equivalent to a Phase I project has been met. Documentation can include data, reports, specific measurements, success criteria of a prototype, etc. </p> <p>Refine the preliminary design proposed in the solicitation and create a prototype of a low-altitude passive detection system.

System refinement should include integration of the solution into identified Army reporting systems. Required Phase II deliverables include two prototype systems inclusive of the components (hardware and software) necessary to leave behind for end user experimentation. The prototype will be demonstrated at a government-approved location to evaluate performance.

Additionally, the performer will deliver monthly progress reports describing technical challenges, risk, and progress against the schedule. At the end of the period of performance, the performer will conduct a final demonstration and submit a final technical report.

</p> <p>The concept of passively sensing threats of various velocities at low altitude has already been realized with the commercial availability of several passive sensor technologies. Radio Frequency (RF) sensors include those with ranges up to 8km and others with 360 degree detection capacity. Other sensors include optical and thermal sensors that employ HD cameras.

This DP2 SBIR will facilitate the integration of multiple sensors and/or the refinement of sensors to yield the desired capabilities that will inform and address knowledge gaps for the Army Long Range Persistent Long Range (ALPS) Program.

</p> <p>Commercial applications for passive detection systems include: perimeter security for large facilities, air traffic control augmentation, maritime surveillance, border monitoring, environmental monitoring, and even crowd analytics by leveraging existing radio signals from sources like cell phones or broadcast TV to detect movement without emitting any radiation themselves, offering a covert and cost-effective surveillance option.
